What exactly do you need to analyze? I guess you have forgotten to add the lines. Our answers would be more helpful.
Grendel is depicted as an evil mindless monster whose only goal is destruction and spreading evil. Considering that he's not depicted as an intellectual tactician but rather as a brute who wants to eat others, he would probably just heal up and attack again. Either that or he would ask for help from his mother.
Its from ''To Kill a Mockingbird" and Atticus tells that line to scout.
In my view purpose and point of view are very important when writing a biography.
